Chemical Structure
Description
3-Bromo-4-(4-ethylcyclohexyl)benzoic acid (CAS 1131622-57-5) is a high-purity analytical reference standard with the molecular formula C15H19BrO2 and a molecular weight of 311.21 g/mol.
Based on its molecular formula C15H19BrO2, 3-Bromo-4-(4-ethylcyclohexyl)benzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Bromo-4-(4-ethylcyclohexyl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
